SSC GD Constable (English) - 10 Jan 2023 - Shift 3 • Quantitative Aptitude • Q52

What is the difference between the compound interest on Rs.5,750 for one year at 16% per annum compounded yearly and compounded half-yearly?

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. Rs.36.80

Sum = Rs. 5750

Rate = 16%

Yearly rate of 16% for one year = 16%

Half-yearly rate = 16/2 = 8%

Compound interest for one year = (x + y + xy/100)%

Compound interest for one year at 8% = (8 + 8 + 64/100)% = 16.64%

Difference of yearly and half yearly interest rate = 16.64% - 16% = 0.64%

0.64% of 5750 = 0.64(5750)/100 = 36.80
